On 4.1.4 on Ubuntu 18.04, I’m getting
/tmp/.mount_QGroun4BUfNy/QGroundControl: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by /tmp/.mount_QGroun4BUfNy/QGroundControl)
/tmp/.mount_QGroun4BUfNy/QGroundControl: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by /tmp/.mount_QGroun4BUfNy/QGroundControl)
But this doesn’t happen on 4.1.2 or daily build, which both run normally.
